The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Solution to the problem
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
Part a
We want this probability:
Using the probability mass function we got:
Part b
The expected number are:
Part c
We want this probability:
And we can find the individual probabilities and we got:
And after replace we got:

Answer:
The correct option is 1.
Step-by-step explanation:
In a graph, the lowest points of the functions are called local minima and highest points of the functions are called local maxima.
The point of local maxima and local minima can be more than one point. The graph must be continuous at extreme points.
From the given graph it is noticed that the highest point of the function is (0,1), therefore the local maxima is (0,1).
The lowest points of the graph are
But the graph is discontinuous at . So, the point is not a local minima.
The point of local minima are .
Therefore option 1 is correct.
